They help researchers find answers by allowing them to look at a problem in a new way, from a different perspective.They help to better understand a process, trace a compound from a particular source, measure the concentration of a chemical in a sample, or measure the rate of a related process.

A bar of pure uranium, for instance, would consist entirely of atoms with atomic number 92.

The periodic table of the elements assigns one place to every atomic number, and each of these places is labeled with the common name of the element, as, for example, calcium, radon, or uranium.

In spite of an apparent high degree of variability, the literature continues to focus on modern and classical stereotypes rather than the rich variability in the Egyptian mummification tradition.

Detailed, large-scale examination of this and other mummification traditions, and their meanings, is required to further our understanding of this important early complex society.

Uses of stable isotopes include the custom synthesis of new and complex labeled compounds to use in agriculture, biology, chemistry, drug testing, geology, health, nutrition, physics as well as diagnostic techniques in medicine.

» View Examples of Stable Isotope Compounds Many of the chemical elements have a number of isotopes.An "isotopically labeled compound" has one or more of its atoms enriched in an isotope.Stable isotopes are tools used by researchers worldwide in the diagnosis of disease, to understand metabolic pathways in humans, and to answer fundamental questions in nature.The numerical difference between the actual measured mass of an isotope and A is called the mass defect.The specification of Z, A, and the chemical symbol (a one- or two-letter abbreviation of the element's name, say Sy) in the form A/ZSy identifies an isotope adequately for most purposes.Some radioisotopes are manufactured in a cyclotron in which protons are introduced to the nucleus resulting in a deficiency of neutrons (proton rich).
